To all whom t may conce-rn.' *i

lle it known that l, OLIVER D. JOHANT- GEN, a citizen of the UnitedStates, and resident of Lake Bluff, county of Lake, and State otllllinois, have invented certain new and useful improvements in Nonaddand 'lotaldey Mechanism for Listing Machines,

of which the following is a specilication,

and which are illustrated in the accompanyl ing drawings, forming a partthereof.

The invention relates to listing machines,

and has for its object to simplify and improve the mechanism employedfor controlling the movements of the accumulator into l5 and out ofengagement with the actuating racks. For the purpose of illustrating theinvention the improved mechanism has been applied to the'listing machinecommercially known as the Victor Adding Machine, as shown in Patent No.1,336,840, dated April ln the accompanying drawings:

Fig. l is a side view, principally in elevation but partly in section,showing the improved non-add and total key movements, some features ofthe machine not pertaining to the invention being omittted entirely orpartly broken away; Y Y

Fig. 6 is a perspective view showing a key which may loe used inconnection with the locking mechanism illustrated in Figs. 3, l and 5;and

Fig. 7 is a section on line 7-2 of llig. l.

ln so far as the present improvements are concerned the accumulator,generally designated 10, the movable racks, as ll, and the item andtotal printing mechanism, generally designated l2, are or may 'neidentical with the corresponding parts oi the machine illustrated inPatent No.' 1,336,840 already mentioned. Likewise, the present machinealso includes an oscillating control shaft 13, which turns in onedirection during the outward movement ot the racks, as ll, and` in thereverse direction during the return move-` ment of the racks. f

ln the item printing and accumulating operations of the machine the`register wheels, as lei, of the accumulator are sup# ported out oi-thepath of the racks, as l1, during their outward movement, but are loweredinto osition for engagement with the racks during inward movement ot thesame, while in total taking and printing the said register wheels, as14, are lowered at the beginning of the operationior engagement with theracks during their outward movement. ln printing a non-add item theaccumulator 10 1s idle, its register' wheels, as lll, being supportedlout of the path ot the racks, as l1, during the entire operation. Thesaid special operations of the machine, viz -total taking and printingand non-add item printing, are controlled as usual by the depression ot'total and non-add keys l5, 16, respectively. When a sub-total is to beprinted the total key 15 is released at the v end of the forward strokeci the handle not shown). i

llaising and lowering the accumulator 10 is permitted lay mounting thespindle, as i7,

upon which the register wheels la are jour-` naled, in a 'trame 18.rllhis trame is supported at `its op osite ends in hell-crank levers,one ot whlch is shown at 19. Bellcrank lever 19 is pivoted to a lined'su portv at 20, andthe movements of the spin le ll' are conlined to avertical plane by the extension oit the ends ot the spindle throughvertical slots, as 21, in affixed part of the iframe.. A spring 22reacts between one arm ot the hell-crank lever 19 and a xed supV inelevated position.

Movement is transmitted to the accumulator l0 trom an oscillatirwF plate23, jouru naled on a fixed stud 2l. s shown, a link 25 connects theplate 23 with one arm ot port to normally support the accumulator thehell-crank lever 19. A light spring 26,

reacting loetween the link 25 and the plate 23, and connected to theplate at a greater distance from the stud 24 than the link 25, acts in'opposition to the spring 22. Fur'- tliermore, link -25 is preferably sopositioned that when the accumulator .has been depressed loy a forwardswingingmovement ot the plate 23, link 25 is so nearly aligned with stud2l that spring 22 is inedective to i restore the accumulator` tion. Y

The swin ing-of the plate 23 is accomplished by t e coaction ot a pairof links A to elevated pesi- 27 and 28 with two wrist pins 29 and 39,

carried by a Hanged disk 3l, mounted upon .the adjacent end of thecontrol shaft i3.

In the form shown, the two links 27 and 28 have a common pivotalconnection with the Vplate 23 at 32. A. spring 33 connects the links 27and 28 intermediate their ends,

' and both links have sliding engagement with a bracket plate 34, formedon the stem of the total key 15, the said bracket plate 34 normallysupporting the link 27 and limiting the upward movement oit the link 28by the spring 33.. rlhe link 28 also 'entends in the path of a stud 35mounted on the stem of the non-addikey 16. @n depression er the totalkey l5 both links 27 and 28 are lowered, link 28 being directlyydepressedby the bracket'plate 34, and the lowering of bracket plate34permitting thedepression of link 27 by theispring 33; Upon depressionot the non-add key l, link 28 is depressed by the engagement therewithof stud 35, l y y ln the normal operation of the machine, viZ:-in itemprinting and accumulating, wrist pin 30 is idle. lin these operations.link 28 is depressed and passed by wrist-prin ment of the control shaft13, both links areV returned and the accumulator elevated by ftheengagement of wrist pin 29 with a forwardly facing shoulder 36 onlink27.

During the interval between the engagement'of wrist pin 29 with the endof 28, andy the engagement et this wrist pin with the forwardly lacingshoulder 33 en link 27, the accumulator l0 is heldin depressedpositionbyspring 26, the stronger spring 22 being ineffective to raise the samebecause ot the said direct alignment of link 25 With stud 24. rllheregister'wheels,

- as 14,' of the accumulator are accordingly held in the path oftheracks, as ll, during the return or inward movement oit the racks.

'llhe part, as 37, ot link 27 having the forwardly facing shoulder 36,takes the form of a dependinggfinger. Preferably this linger has arearwardly lacing beveled end 35, tor cam engagement with the wrist* pin30, to raise the link. However, this raising ot link 27 by wrist pin 30is merely .for the purpose ol permitting the wrist pin to come to restbeneath the n'ger 37, the

parts being so proportioned that wristy pin 30 never passes beyondthenger; l

Y In taking a total o rV sub-total, link 28 is idle,` the saiddepression oil this link by the total keyV l5 serving to move the linkentirely out ot the' path of 4wrist pin 29.

Furthermore, in taking a total thereis no v operative -engagement.. witheitherl of the wrist pins 29 or 39 with any part of the nger 37 on 'link27. On the contrary, movement ot the accumulator 10, tor totalA takingis accomplished by the engagement el' wrist pins 29 and 30 withoppositely facing shoulders 39 'and 40, respectively, on

link 27. As shown, these shoulders are too short to extend into the"path ot the wrist pins 29 and 30 except when the link 27 is lowered-bythe depression of the total key l5. ln order'that the accumulator l()may be lowered during the outward movement oit the racks,l as ll,shoulder 39" is located in front ot the linger 37 for engagement withatthe beginning of the returny movement of the control shalt. 'lhe rearend of link I 27 is accordingly beveled, as at 4l, for cam engagementwithwrist pin. 39 to raise the link `27 and Apermit the wrist pin tomove to a position in liront of shoulder 40, as this wrist pinapproaches the end` of its forward movement.

ln case the total key l5 is released at the end ot the forward movementof the handle (not shown) for taking a sub-total, the accumulatorremains in lowered position until the end ot the return stroke oit :thecontrol shaft l3, when it is raised by 'contact olf wristpin 29 withforwardly lacing shoulder 33, as in the item printing and accumulatingoperations of the machine.

llhen tot-al taking is to be prevented, except by authorized persons,locking mechanism, preferably controlled by a removable key, as 42 (Fig.ti), may be provided tor holding the total key l5 against movement. Asshown, an escutcheon plate 43, having key hole, is mounted on the keyboard 44 immediately adjacent the total key 15, while fiat swinging bolt45, having a socket 46 conforming in shape with the end ot thc key 42,is pivotally supported under the key board 44 in line with theescutcheon plate 'Preferably the 4bolt 45 'has its pivotal supportindependent of the keyboard 44, as upon a ixed bracket or shelf 47. lnthe simple form of lock illustrated, the bolt 4.5 y

swings in its own plane and coacts with a notch 48 formed in thead]acent edge of the total key 15, the movements of the bolt in bothdirections being limited by the location.
